Problems solved by technology

For the user equipment currently allocated resources, because the resource blocks allocated by the network may be discontinuous, the network may send control signaling to the user equipment at multiple resource block positions, so the user needs to detect all possible control signaling Even if it finds its control information in a resource block, it still needs to traverse all possible resource blocks, resulting in greater complexity and the possibility of false detection
[0013] 2) The second method as shown in FIG. 4 solves the problem in FIG. 3 to a certain extent, that is, the control information of the network to a user equipment is sent in one resource block, but assuming that the number of system resource blocks is N, The average number of detections is N / 2, and the detection overhead and the possibility of false detection are still relatively large
For users who are currently not allocated resources, it still needs to sequentially detect all resource blocks in the network to determine that the network has not sent control signaling to them, which has high processing overhead and the possibility of false detection increases

Embodiment

[0082] This section gives six embodiments of the present invention. In order to avoid making the description of this patent too lengthy, in the following description, detailed descriptions of functions or devices that are well known to the public are omitted.

no. 1 example

[0084] In this embodiment, the network sends the continuous grouping information of the currently allocated resource blocks on the common control channel; and the network sends the user equipment identification and other control signaling allocated to the resource blocks in each group of resource blocks respectively. It is assumed here that the resource blocks allocated by the network to the user equipment are allocated consecutively.

[0085] In the example shown in FIG. 7 , the number of resource blocks that can be allocated in the network is N=12. The network allocates resource blocks 701, 702 and 703 to user equipment 1, resource blocks 706 and 707 to user equipment 2, resource blocks 708 to user equipment 3, resource blocks 710 and 711 to user equipment 4, and Resource blocks 712 are allocated to user equipment 5 . Resource blocks 704, 705 and 709 are not allocated in the current subframe. In this way, the number of consecutive groupings of resource blocks is M=7, and r...

no. 2 example

[0090] In this embodiment, the network sends the continuous grouping information of the currently allocated resource blocks on the common control channel; and the network sends the user equipment identification and other control signaling allocated to the resource blocks in each group of resource blocks respectively. It is assumed here that the resource blocks allocated by the network to the user equipment may be discontinuous.

[0091] In the example shown in FIG. 8 , the number of resource blocks that can be allocated in the network is N=12. The network allocates resource blocks 801, 802, 803, 810 and 811 to user equipment 1, resource blocks 806 and 807 to user equipment 2, resource blocks 808 and 812 to user equipment 3, resource blocks 804, 805 and 809 Not allocated in the current subframe. In this way, the number of consecutive groupings of resource blocks is M=7, resource blocks 801, 802 and 803 are a group (815), resource blocks 804 and 805 are a group (816), which is ...

Abstract

The present invention relates to a method of the transmitting and controlling signaling, comprising the following steps: the network distributes resource blocks for all user devices; the network sends the current information relative to the resource blocks on the public controlling channel and the network sends marks of the user device and other controlling signaling on other channels. Adopting the present invention can effectively reduce the times of the blind inspections of the user devices, thereby reducing the complexity for the user device receiving the controlling channels and reducing the probability of the occurring of the mistake inspections.

Description

technical field [0001] The present invention relates to a wireless communication system, and more specifically relates to a device and method for transmitting control signaling in a wireless communication system. Background technique [0002] Now, the 3GPP standardization organization has embarked on the long-term evolution (LTE,) of its existing system specifications. Among the many physical layer transmission technologies, the downlink transmission technology based on Orthogonal Frequency Division Multiplexing (OFDM) and the uplink transmission technology based on Single Carrier Frequency Division Multiple Access (SCFDMA) are research hotspots. OFDM technology is essentially a multi-carrier modulation communication technology. Its basic principle is to decompose a high-rate data stream into several low-rate data streams and transmit them simultaneously on a group of mutually orthogonal sub-carriers. OFDM technology has performance advantages in many aspects due to its mul...
